A skateboard comprising a rigid elongated board having front and rear portions, and front and rear wheel trucks mounted to the underside of the board. The wheel trucks each have multiple wheels mounted in-line. A steering platform is at the front of the board for use by the rider to steer the board. The steering platform is rotatable and is connected by a linkage system to the wheel trucks wherein, by rotating the steering platform, each wheel within their respective truck is equally angularly displaced to effect a turning movement of the board.
